In the drawings, wherein for the purpose v of illustration is shown avpre`ferred embodiment of my invention, attention being called at first to Figs. 1, 2, 3, 4:, and 5, the numeral 15 designates a base-plate. This base-plate is provided withv a central cylindrical opening 16, receiving therein an outer tubular rotatable' and reciprocatory member `17, the forward end of which is provided with a recess or -chamber 18., normally covered by a cap 19, preferably Vhaving screw-threadedengagement therewith, as shown at 20. The

' opening 22', to register with the opening 17.

Surrounding the, outer tubular member 17 is a stationary annularholding flange 25, (Fig. 2) preferably formed integral with the base 15. The flange 25 is provided with a shoulder 26, to contact with the flange 24, as shown. This shoulder constitutes the end wall of an enlarged screw-threaded bore 27 of the flange 25, provided with a longitudi- .nal groove 28, for the reception of a key or extension 29, formed uponthe ange 24. It

is thus apparent that means are provided to lock the inner tubular member 22 to the flange 25, against rotation with respect Y thereto.

The numeral 30 designates a locking ring, which is L-shaped in cross-section and screwthreaded to engage Within the screwthreaded bore 27, as shown. This locking ring serves to hold 0r lock' the'inner tubular member`22 within or to the flange 25.

The numeral 31 designates an insulating sleeve, projecting into the inner tubular member 22, and carried by an insulating head 32, arranged upon the flange 24 and clamped thereto by the ring 30, as shown. The head 32 is provided with an opening 33, for the purpose to be described.

The numeral 34 designates a casing, constituting the body portion of the apparatus,

and this casing is secured to the base 15 by lneans to -be described. The casing 34 lnay be attached to a stationary support or dash 35, by lneans of brackets 36 or the like.

Arranged Within the casing '34, at dialnetrically opposite points, are brackets 37, attached thereto, as shown at 38. These brackets are approximately L-shaped and are provided at their ends with flanges 39 and 40, as shown.

The numeral 41 des1gnates an approximately U-shaped bracket (see Fig. 2) having transverse end portions 42 and 43. The end portion 42 is attached to a lock or flange 44, formed upon the inner side of the base 15., by means of a screw 45 or the like. The end portion 43 is provided with an extension or lip 46, adapted to be inserted within an opening 47, formed in a lock or flange 48, carried by the inner side of the base 15. It is thus apparent' that the bracket 41 is securely attached to the base 15. Attached to the longitudinal portion of the bracket 41 are guide pins or rivets 49 (see Figs. 2 and 8) operatlng within longitudinal slots 50, formed in a pair of reciprocatory bolts 51. These bolts have their inner ends reduced for substantially onehalf of their width, providing extensions 52, arranged side by side-overlapping and carrying laterally extended heads 53. One head 53 is provided with a .screw-threaded opening to receive the reduced screwthreaded portion of a screw 54, while the other head 53 is provided with an enlarged smooth opening for receiving a smooth portion of the screw. A compressible coil spring 55 is arranged between the heads 53, thus tending to force the same away from each other, and dra-w the inner ends of the bolts 50 inwardly, The .screw 54 is equipped with a head 56, and access is had to this head through an opening 57, in the casing. 'The screw 54 carries astop nut 54', as shown. The extensions 52 are provided with semicircular openings 58 (see Fig. adapted for registration, when the bolts 50 are in. the

outer holding position for the purpose to be described. The outer ends of the bolts 51 are adapted to' engage inwardly of or behind the flanges 39 (seeFig. 2) thereby serving to lock the base l5 and elements carried thereby, to the casing 34. A

Means are provided to normally lock the outer tubular member 17 against forward 'longitudinal movement, comprising' a rod 59, extending longitudinally within and through the inner relatively stationary tubular nieln'ber 22 and having a swiveled ,connection with'the recess or chamber 18,

as shown at 60. The rod 59. is provided with laterally extending lugs orbits 61 and 62. The rod 59 is provided upon its rear end with a lock-extension 59, to enter the registering openings 58, as .shown in Fig. 3.

Thenumeral 63 designates tumblers (Fig. 2)Which are pivoted Within the stationary tubular member 22. These tumblers have key-hole openings 64, adapted for the reception of the rod 59 and the bits 62 thereof.

62 moves completely out of the key-hole opening 70 the bit 61 is moved therein,

whereby the rod '59 is permanently prevented from rotating upon its longitudinalv axis. The lnember 68 is provided upon its periphery With lugs or keys 71 (see Fig. 10), adapted for insertion within grooves 72 formed upon the interior of the stationary tubular melnber 22 It 'is obvious-that before the rod 59 can be moved forwardly, the tumblers 63 lnust all be turned so that their key-hole openings are in alinement with the key-hole opening 70 and by turning themember 68 to shift the radial position of its key-hole opening 70, the position that the tulnblers must be lnoved to bring all key-hole openings into alinernent, is accordingly changed. By this means the combination may be changed or set.

The switch apparatus comprises an annular rotatable contact carrying member 73, having a ange 74, pivoted u-pon the stationary flange 25. A. 'portion of the flange 74 is c ut away for receiving a segmental gear 75,'` operating Within a slot or opening 76 formed in the stationary flange 25, as shown in Fig. 2. This slot is made sufficiently long to permit of the desired extent of lnove- )nent of the nielnber 73. The teeth of this gear 75 project into the flange 25 and are bile.

adapted for engagement with the teeth 2 1, when' the outer tubular member 17 is drawn forwardly, whereby the annular contact oarrying member 73 will turn upon the turnlng movement of the member 17. This Contact carrying member '43 is provided with any .suitable number of contact segments 77 disposed upon the inner and outer sides thereof, and adapted to be moved into electrical contact with pairs of coacting contact strips 78, attac-hed to binding posts 79.

These binding posts are secured to a stationary member 80, formed of insulating material, and rigidly secured to the' flanges 40, as shown lat 81. The binding posts are adapted for connection with wires (not shown) which may be passed in through an opening 82 in the casing 34.

The numeral S3 designates binding posts, having connection with contacts 84, as shown in Fig. 3, and these contacts normally engage contacts 85, extending forwardly for providing terminals 86. terminals are adapted to be electrically connected by a contact segment or ring 87, carried-bythe rod 59 and insulated therefrom, It is thus apparent that the circuit will be Closed when the rod is moved forwardly sufficiently to bring contact 87 into engagement with contacts 86.

The numeral 88 designates a hand wheel, secured to the shaft 88 (see Fig. 2a), pivoted to the base 15 and extending inwardly beyond the same. Rigidly secured to the inner end of this shaft 88 is a forked-crank 89, shown more clearly in Fig. 2, This forked-crank is adapted to project into av recess in the member 74: and to engage with a pin 90', rigidly secured to the outer p0rtion of the member 74. When the member 74 is in the normal -position, the forkedcrank 89 will engage with .the pin 90 and the hand wheel 88 will be capable of turning the melnber 7-1 for a restricted distance, which may be employed to turn on or off certain circuits, without operating the combination, provided the member 74.- is in 'the starting or neutral position.

The apparatusA shown and described is particularly well/adapted for opening and closing circuits employed .upon an automo- Thus the contacts 86 and 87 may be employed to open and close the circuit for starting the engine while the other contacts may be employed for controlling the various circuits for the lights and the like. However, it is obvious that the invention is in no sense restricted to this particular use.

-In assembling the various parts of the apparatus, the screw 54 is unscrewed, and this unscrewing movement is limited by the nut 54, contacting with one head 53. As

the screw is unscrewed, the spring 55 forces the heads apart, whereby the ends of the 51 become positioned inwardly of the bolts Theseturning the tubular Y casing,

I flanges 39. The base 15 may then be placed upon the casing 3-1, and the rod 59 should be in the forward position with the conibination open. A screw driver may now be passed through the opening 57 and the screw turned to screw the same up whereby such screw will serve to move the heads 53 toward each other, and thebolts 51 will be moved outwardly so that their outer ends catch behind the 'flanges 39, therebyserving to lock the base to the casing. When the rod 59 is shifted to the rear or inner position, the extension 59 thereof will pass into the openings 58, which are now in registration. If the combination is now set or locked it is obvious that the bolts 51 cannot be moved inwardly,.by the expansion of the spring 55, if the screw 56 is unscrewed, whereby the base 15 and casing 34 are locked together prior to the operation of the 'combination. l Y In the operation of the apparatus, the rotatable tumblers 63 are turned until the propel' reference characters 63 'constituting the correct combination, are brought in alinement, at which time the bolt 59 lnay be moved forwardly. The longitudinal movement of the bolt may operate a circuit and various other circuits may be operated by member 17,` upon its longitudinal axis.

It is to be understood that theform of my invention herewith `shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement Ofparts may be resorted vto without departing from the spirit of the invention or the scope of the subjoined claims. v
